Problems solved by technology

However, the cushioning material made of paper does not have the recovery force of the void after punching, and the constituent fibers are thermally deteriorated, so there is a disadvantage that it cannot be used repeatedly after multiple punching.

Abstract

The invention discloses a novel buffer pad which sequentially comprises a surface layer, a first thick cloth layer, a first thin cloth layer, a second thick cloth layer, a second thin cloth layer, a third thick cloth layer, a third thin cloth layer, a fourth thick cloth layer, a fourth thin cloth layer, a fifth thick cloth layer, a fifth thin cloth layer and a sixth thick cloth layer from top to bottom, wherein the surface layer comprises a polytetrafluoroethylene layer, a glass fiber cloth layer and a fluorine rubber layer containing pores in the fluorine rubber layer; the first thick cloth layer is prepared by dipping glass fiber cloth into liquid fluororubber and curing the glass fiber cloth; and the first thin cloth layer is made of fluororubber with air holes inside. The novel bufferpad is composed of the glass fibers and the fluororubber containing the air holes, has the outstanding advantages of being excellent in buffering performance, good in heat resistance (capable of beingused for a long time at the high temperature of 240 DEG C), low in deformation rate and the like, and is a high-performance buffer pad material superior to a traditional pressing pad and kraft paper.

Description

technical field [0001] The invention relates to the technical field of cushioning materials for hot pressing, in particular to a novel cushioning pad. Background technique [0002] In the process of manufacturing laminates such as printed circuit boards, in the process of stamping and thermocompression bonding, the laminate material as the object to be pressed is clamped between hot plates as the heating and pressing mechanism, and a certain pressure is applied. pressure and heat. In order to obtain molded products with good precision, in order to uniformize the heat and pressure applied to the laminate material throughout the hot press, it is necessary to perform hot pressing with a flat cushion material interposed between the hot plate and the laminate material. [0003] In the prior art, a paper material made of kraft paper or cotton linter paper laminated with about 3 to 20 sheets is often used as a cushioning material for hot pressing. In addition to being inexpensive...
